River Estuary Coastal Ocean Estuaries Draw picture Estuary: is a body of water, partially enclosed by land, where fresh water from a river mixes with salt water from the ocean. Water in Estuaries is Brackish. Brackish means partly fresh and partly salty.
Neuse River Estuary Very Salty Neuse River Very Fresh
NC largest Estuary is the Pamilco Sound Neuse River
Filtering System • Estuaries clean our rivers by removing….. Sediment and Pollutant. This makes me think of…______
Sediments • Sediment – Soil particles and chemicals carried by the river • Carrying of soil Muddy estuaries • Soil can smother fish eggs, aquatic insects, and plants with mud. • Erosion of land Chemical deposits • Chemicals can kill life
Some estuaries are actually salt marshes. • These plants and mud take up some of the sediments and pollutants! • Animation of salt marsh • Salt Marsh Filtering • http://oceanservice.noaa.gov/education/kits/estuaries/media/supp_estuar03a_marsh.html
Pollutants • Pollutants: Pesticides, sewage and industrial waste • Estuaries are a type of environmental filter. • Plants and animals in estuaries filter pollutants out of the water.
Pollutants • Ex: Salt Marsh Plants trap some of the chemicals and pathogens carried by rivers and move them into soils where they can be neutralized. • Ex: Oysters filter impurities out of the water as they eat, collecting contaminants in their bodies. One oyster can filter 25 gallons of water per day
Too many toxins can accumulate in estuaries causing many environmental and health problems
